Is J1* present in ethnic Iranians or is it restricted to Assyrians and Armenians in iran? Is it native to them(or did they get it from mixing with armenians, north Caucasians, assyrians etc) and how did it get there?

What about J1-P58? How did it get there?

Is J1b native (ie stemming from a known population movement or neolithic wave ) to northern iran?

How did P58 get to Ireland pre 1714 ?...no hard answers to specific questions the farther you get from the middle east I'm afraid. If so, I would love to hear specifics, cuz I've been floundering around for a few years now on this one.
